| 摘 要： | 针对弹载雷达系统仿真速度较慢的问题,提出一种适用于弹载雷达系统的快速回波模拟算法。新算法引入了慢时间的概念,重新推导了雷达回波的表达式,以相参雷达为例,比较了新算法与常规回波模拟算法的运算量,分析了两种算法的等价约束条件。仿真实验结果表明,新算法比常规算法运算量小,并在满足一定误差要求的情形下与常规算法等价。

| Abstract: | In order to obtain the rapid simulation of the radar system,a new echo algorithm for missile-borne radar system is presented in this paper.A concept of time called slow time is adopted in this new algorithm. A new function of radar echo can then be derived. The constrained equality and the comparison for the operational quantity between the original algorithm and the fast echo algorithm are studied.Simulation results demonstrate the validity of the proposed algorithms.The algorithm can effectively improve the efficiency of simulation. |
